a) 13) Online the timing and tailoring of prices to specic models of products is the key to successful pricing in online markets. And \"Thanks to the ready availability of data in online markets, a pricing manager can easily approximate the elasticity of demands for the different products it sells online.\" Assuming a 10 percent decrease in price increases sales by 25 percent, calculate the price elasticity of demand? If the wholesale price of the online product is $50 and sells at a price comparison site that charges $.50 per click and boasts a conversion rate of 5 percent (an average of 20 clicks are needed to generate a sale), the incremental cost of each sale is $60. What price should you charge for the product? What is the optimal markup? The authors assert that price sensitivity is affected by (1) product life cycles, and (2) numbers of competitors. In fact, \"when the number of competing sellers doubles, a firm's elasticity of demand is expected to double (and you should be able to verify this through experimentation?) Assuming the price elasticity you calculated in Problem 1 doubles, what is the new optimal markup? What new price should you charge for the product
